【Abstract】 New hybrid precast concrete shear walls( NHPW) utilize the unbonded post-tensioned tendons,lap-splice grout vertical connecting reinforcements,and the overlapping welded closed stirrups.NHPW possesses good deformation restorability,energy dissipation capacity and ductility to emulate the cast-in-place monolithic shear wall in seismic performance. The configuration,working mechanism and test research results were discussed and suggestions were then put forward.更多还原
